FEATURES
Description: The synchro check relay type SYND is a multifunction unit that can be set to both constant or pulse output as well as to enable or disable synchronization to a “dead bus”. The unit is designed with a micro controller to monitor the bus and the generator voltage, as well as the phase differential between two grids.

For a front panel indication of the function, the SYND can be connected through a simple three wire digital interface to the optional panel indicator type SYPD.
Dead Bus ON: Be careful when this function is selected. Personal injury can occur if the bus is disconnected for maintenance. Too the load of the generator can be excessive. When the Mains Bus voltage is detected to be under the Dead Bus VDB% set limit V the Mains Bus is defined to be dead and the internal relay will pull in if the Generator voltage is above 75% of nominal value. The relay will drop out or stay in according to the function setting on the SYPD as described above.

The unit is specially designed for DIN rail mounting on the base of the control box for an easy connection to the two bus systems.
Operation: Dead Bus OFF: When the voltage on the Mains Bus, L1 - L2, and the Generator Bus, L1 - L2, both are above 75% of the nominal value, the SYND will monitor the voltage difference ∆V%. As soon as ∆V is below the set limit, the SYND will start monitoring the phase difference ∆ϕ. If the phase difference ∆ϕ is continuously below the set limit during the elapse of the set delay time td, and the voltages still within the limits, the internal relay will pull in for 100 m sec. if pulse output is selected, or stay in as long as the conditions are within the limits for synchronisation.

The SYND ensure the right conditions before the connection of the generator to the bus, in order to avoid damage to the generator and malfunction or damage to the connected equipment.
